Determine how many videos you can store on a memory card by calculating the total capacity based on video resolution, duration, and file format. This calculator helps photographers, videographers, and content creators plan their storage needs efficiently.
How the Calculator Works
The memory card video capacity calculator estimates the number of videos you can store based on three key factors:
- Memory card capacity - The total storage available on your memory card (in GB or TB)
- Video resolution - The quality of your videos (e.g., 1080p, 4K)
- Video duration - How long each video clip is (in minutes or seconds)
The calculator uses these inputs to determine how many complete videos can fit on your memory card. It accounts for different file formats and compression settings that affect file sizes.
The Formula
The calculation follows this formula:
Number of Videos = (Memory Card Capacity × 1024) ÷ (Video File Size × Video Duration)
Where:
- Memory Card Capacity is in GB (converted to MB for calculation)
- Video File Size is the average size per minute of video in MB
- Video Duration is in minutes
The calculator uses standard video file size estimates for different resolutions and formats. You can adjust these values if you have specific compression settings.
Worked Example
Let's calculate how many 1080p videos you can store on a 64GB memory card:
- Memory card capacity: 64 GB
- Video resolution: 1080p (1920×1080)
- Video duration: 5 minutes
- Average file size for 1080p: 30 MB per minute
Number of Videos = (64 × 1024) ÷ (30 × 5) = 65,536 ÷ 150 ≈ 437 videos
This means you can store approximately 437 five-minute 1080p videos on a 64GB memory card.
Frequently Asked Questions
How accurate is this calculator?
The calculator provides an estimate based on average file sizes. Actual results may vary slightly due to different compression settings, metadata, and file system overhead. For precise calculations, check your specific camera's file size documentation.
Does this work for all memory card types?
Yes, the calculator works for any memory card type (SD, microSD, CF, etc.) as long as you know its total capacity. The calculation is based on the card's storage capacity, not the type.
Can I use this for RAW video files?
RAW video files are significantly larger than compressed formats. The calculator provides estimates for common compressed formats. For RAW files, you should check your camera's documentation for specific file size information.
How do I find my memory card's capacity?
Check the label on the memory card or use your device's file manager to view the total storage capacity. Most operating systems will display this information when you insert the card.
